Wish I could afford ozempic but it's too expensive and i can't get it free because im not diabetic.

Join the gym? Get active. Do 1 hour of cardio every day. Even if it’s just walking in your neighborhood. Cut sugary and fats from your diet. If you drink regular coke , switch it to Diet Coke. If you eat fast foods , get the healthier options from the menu. I don’t know about where your live, but Tacobell has an option called “ power bowl” that has all the healthy nutrients you need without eating a ton of fats. Start following people on social media who have the same goal as you, people who teach workouts, how to prepare healthy food options , etc. Use social media in your favor. If you can’t afford to pay for a gym membership ( even though I’d suggest planet fitness for starters, it costs like $14 a month) ,start working out in your room or in your backyard , buy a yoga mat, do strength exercises, buy a jump rope. You can even get affordable treadmills from Amazon for around $225.
As per diet, be mindful of what you eat. Replace sugary and fatty foods with fruits, veggies ( Walmart has them really affordable) . Choose always a sugar free version of the things you like. If you have medical insurance, see if they can cover you visits with a dietitian ( most insurances cover it nowadays). There are many things you can that don’t require Ozempic. It may take a little longer , maybe 6 months to a year to see great results, but with consistency and determination you can get there.
Also don’t focus on being a size this or that. A size 0 won’t look good on everyone. If you have a large bone structure it will look odd. So focus achieving a healthy weight , reaching your ideal BMI levels. So that way, not only you’ll look better, you’ll live longer. And have more quality of life.
